A Study on Intelligence of High School Students

Assignment: Article Critique

undefinedThe practice of quantitative research not only involves statistical calculations and formulas but also involves the understanding of statistical techniques related to real-world applications. You might not become a quantitative researcher nor use statistical methods in your profession but as a consumer, citizen, and scholar-practitioner, it will be important for you to become a critical consumer of research, which will empower you to read, interpret, and evaluate the strength of claims made in scholarly material and daily news.

For this Assignment, you will critically evaluate a scholarly article related to reliability, validity, and scale analysis.

To prepare

Review the Article Critique Assignment Guide in the Walden Library, listed in the Week 2 Learning Resources.
Search the Walden Library for a quantitative article that utilizes scales.

The Assignment

Write a 2- to 3-page critique of the research you found in the Walden Library that includes responses to the following prompts:

Did the authors construct scales in a clear, concise manner?
Were the authors’ explanations clear regarding the reliability and validity of their measures?
What information did the authors provide about establishing reliability and validity?

Learning Resources

Required Readings

Warner, R. M. (2013). Applied statistics: From bivariate through multivariate techniques (2nd ed.). Thousand Oaks, CA: SAGE Publications.

Chapter 19, “Multivariate Analysis of Variance” (pp. 778–828)

This chapter builds on what you have learned in previous weeks about various forms of ANOVA, specifically about analyzing the relationship between several variables on one quantitative outcome variable. Your reading this week will explain how mean scores on multiple quantitative outcome variables are compared for participants across two or more groups.

Datasets

In this course, your instructor will provide you with one dataset (Guided Sample Dataset: Statistics Anxiety) that will be used in several of the tutorial videos. You are encouraged to reproduce the analyses performed in the video using this dataset so you can compare your answers and check your understanding of how to do each analysis in SPSS. You will also be provided with three large datasets for you to use in application of the statistics you’re learning each week. The Statistics Anxiety dataset is not for use in your weekly Assignments. Your instructor may also recommend using a different dataset from the ones we have provided here, which is fine. Your instructor will share these datasets in the Doc Sharing section of the classroom and as an Announcement.
